I have a laser printer which was working fine. Unfortunately the computer to which it was attached (which was running Fedora 12) proved to be sick.
So I've tried moving the printer to two other computers in turn (one 32-bit, one 64-bit) running Fedora 14. I cannot get it to work on either of them.
I get the message:
lp: driver loaded but no devices found
I tried googling which suggested trying:
alias parport_lowlevel parport_pc options parport_pc io=0x378,0x278 irq=7,auto
although this was rather an old message. I tried this and got:
Feb 5 16:14:17 susannah kernel: [ 582.886574] parport 0x378 (WARNING): CTR: wrote 0x0c, read 0xff Feb 5 16:14:17 susannah kernel: [ 582.886579] parport 0x378 (WARNING): DATA: wrote 0xaa, read 0xff Feb 5 16:14:17 susannah kernel: [ 582.886581] parport 0x378: You gave this address, but there is probably no parallel port there!

Now CUPS seems to think the pronter is online, but nothing prints anyway (not surprising in the light of those messages above). (I only actually have one parallel port, but I couldn;t remember which address corresponds to lp0).
Any suggestions?

The parallel interface may be disabled in BIOS.

Thanks Frank. That was indeed the case. Working now.
